- Abstract:
- In the paper a new and original FEM-3D approach to the analysis and design of 20 kV combined current- voltage instrument transformer is given. For the complex study of the electromagnetic field phenomena in the compound configuration with two non-linear magnetic cores of this instrument transformer the finite element method in the three-dimensional domain is used. The FEM-3D derived results will be applied for calculation of the magnetic field distribution in the 3D domain, as well as for the determination of the leakage reactances of the transformer winding. This enables metrologically improved design of the prototype of the transformer, through numerical calculation of the metrological error characteristics of the combined instrument transformer.
